更新时未定义Jqgrid格式化程序rowboject

Question

我在这里根据第二个jqgrid值更新格式化程序中的某些rowobject但是更新时它显示为＆＃34; undefined＆＃34; .how解决这个问题？

                        name:'xx',
                        index:'xx',
                        classes:'xx',
                        width:120,
                        align:'center',
                        sorttype: 'String',
                formatter:function (cellvalue, options, rowObject) 
                            {

                            return "<div style='color:red'><center>"+rowObject.xx+ "(Click here to View Patta Dhaar Details)</center></div>";   

                            }

function dd()
{
var v = JSON.parse(document.getElementById("xx"+sno).innerHTML);
var newpatta=v.curpatta;
var newsurveynewNo=v.surveynewNo;

var currrow= $("#currpattachk").val();

alert("am getting value here"+v.xx);

var cm =  $("#land_details_table_new").getGridParam('colModel');

var rowData = $("#land_details_table_new").getRowData(currrow);

$("#land_details_table_new").jqGrid('setCell', currrow, 'curPatta', v.xx);

$("#land_details_table_new").jqGrid('getLocalRow', currrow).xx = v.xx;
}
